Let me shoot an enemy (or ally for funny trolling tactical manoeuvres) with a harpoon attached to a rope made of handwavium.
The rope should try to winch the target closer or stay at the same length, never get longer (ratchet mechanism???).
Let me then use the dash module or sufficient thrust thing to fling them about, preferably into the ground or a nearby wall at high speed.
Lore justification:
Due to a typo in a logistics form, the system organizing ration distribution skipped a few R&D bases. A group of Osprey engineers didn't get their allotted shipment of food in time and started hallucinating. All of them saw what they thought were Mars whales in the sandy wastes outside the base windows.
They then decided to design a harpoon to hunt said whales.
The medical team sent to check on them reported a wired projectile missing their shuttle by a metre shortly before their arrival.
